From mid-September through November your lawn requires on average half of the water it did in the summer.
If you have the typical heads like this photo you can set your controller to water one day per week. Have your sprinklers run three times in the morning, 10 minutes each time. Setting your controller for start times of 2am, 4am and 6am should allow enough time in between for the water to soak in. If you have rotors (the type of sprinkler that sprays in a long thin stream and slowly turns) you will want to water twice that long or possibly longer. These times are for areas with full sun. In shady areas you can water about half or a quarter of the length of time suggested for sunny areas.
If you have a seasonal adjust spot on your controller you can leave the minutes and days alone and just set the seasonal adjust percentage to 50%.
Not sure what your city’s water restrictions are? Here is a city by city list of links to their water restrictions.
If you need help setting your controller give us a call us or click here and we can probably walk you through the programming over the phone or (of course) we’ll be glad to stop by and set your controller for you. We can also check to see if there are any leaks or clogged nozzles at that time.
